Young women now earn £2,200 more than men, according to a shock report from the Centre for Social Justice (CSJ).
The gender pay gap has reversed, tipping in favour of women for the first time in nearly a decade.
Experts have blamed this sudden shift a "crisis" among boys and young men in Britain. The CSJ think-tank warns that an entire generation of males is "being left behind".
The 'Lost Boys' report states: "There is a crisis of masculinity in this country, a search for what it means to be a young man growing up in Britain today."
Females aged 16 to 24 earn, on average, £26,500 per year. This is nearly a tenth more than their male counterparts on £24,300.
The earnings balance tipped in favour of women for the first time in nearly a decade
GETTYThe earnings balance tipped in favour of women for the first time in nearly a decade in 2021-22. By comparison, just two years earlier, boys and young men had £1,000 more income than girls and young women.
Since then, male wages have stagnated, while female salaries have climbed. Women now earn nine per cent more than men in this age group.
The CSJ describes this dramatic switch as "emblematic of a wider crisis facing British men".
The educational gap begins early, with the CSJ noting: "From the day they start primary school, to the day they leave higher education, the progress of boys lags behind girls."
At age five, 74 per cent of girls met early learning development goals last year compared to just 60 per cent of boys.
By A-level, girls outperform boys by more than a grade and a half across their top three subjects. While boys are twice as likely to be excluded from school.
Once at university, women outnumber men three to two. "At all stages of our education system, boys are behind," the report concludes.
The report blames the loss of "male-dominated industries such as manufacturing, agriculture and construction" for the stagnation in male wages. These sectors once provided "secure, well-paid and meaningful jobs" for non-university educated young men.
The number of men in manufacturing jobs has shrunk by more than 40 per cent since 1997, dropping by 1.3 million.
The number of 16 to 24-year-old males not in education, employment or training has surged by 40 per cent since the pandemic.
More than 40 per cent of adults now think society does not value traditional masculine values. Over half of men aged 18 to 24 believe the media portrays men as "a bit pathetic".
Miriam Cates, a CSJ senior fellow and former Tory MP said: "We have let down a generation of young boys and men.
"For too long, politicians, policy makers, the media and the arts have turned a blind eye to the needs of boys in the name of 'equality'."
She warned that society is "now reaping the whirlwind" from ignoring these challenges.

GETTY"Far from creating equality, we have penalised young men for the crime of being male, labelling them as 'toxic' and 'problematic', and failing to provide a positive vision of masculinity," Cates added.
Andy Burnham, the Labour Mayor of Greater Manchester warned that "too many boys are losing hope for the future in their middle teenage years. They struggle to see where a school system set up to support the university route is taking them," Burnham said.
"Far too many are falling by the wayside."
He described the result as "a disaster in our classrooms, on our streets and in our prisons".
Former England rugby captain Lawrence Dallaglio, who founded the charity Rugby Works, added that young men are treated "as the lowest of the low".
His charity works with excluded schoolchildren, of whom 75 per cent are boys.
"No boys are born bad - they're just born into chaos," Dallaglio said.
